Rovio seems to delight in teasing everyone with Angry Birds
news these days. Just a week after the teaser page for Angry Birds Heikki
opened for business, those tantalising Finns are teasing what looks like new levels for a Facebook version of the game.
At least, that's what the company's tweet suggests. However, the teaser image itself, complete with "coming soon" reference and what looks to be a stadium of creatures, has the intriguing logo 'Angry Birds Friends' in the corner.
A new game, then? An even more social experiment than the current leaderboard-heavy title? Multiplayer, even? Or just simply a new set of levels?
Unfortunately, we're going to have to wait a little longer to find out exactly what Rovio has up its sleeve.
